Beginning today, "Smallville" and The CW are running an innovative contest that gives fans a chance to appear in an upcoming episode. Full details from the official press release are listed below, so work up something creative, grab a camera and submit your entry!

Do you believe in heroes? If so, The CW’s hit series “Smallville” (Fridays, 8:00–9:00 p.m. ET/PT) wants to hear from you. Fans of “Smallville,” from Warner Bros. Television, will have a once-in-a-lifetime chance to appear in an upcoming episode of the 10th and final season via the “Smallville:” Believe in Heroes Challenge, a 10-day promotion running from Friday, December 10—Monday, December 20, on CWTV.com.

• In the episode “Beacon,” to be broadcast on Friday, February 4, Clark (series star Tom Welling) is at an emotional crossroads, with Metropolis divided by a clash between supporters of the government’s Vigilante Registration Act and opposing rallies to generate support for indispensable heroes like The Blur.

• Clark’s friends assure him that he is, indeed, making a difference in his crime-fighting role as The Blur, and to prove their point, they show him videos from the Internet in which ordinary citizens express what The Blur means to them, what it means to be a hero – and what it means to have heroes and believe in them. One of these videos could be yours!

• And this is where “Smallville” fans come in!

Here’s how it works:

• Beginning Friday, December 10, at 11:00 a.m. Pacific Time, and continuing through Monday, December 20, at 11:00 a.m. Pacific Time, “Smallville” fans can submit their own video testimonial as one of these hopeful citizens by uploading videos to The CW’s official website at http://www.cwtv.com/smallville

• In these videos, viewers – speaking in character as impassioned citizens of Metropolis and around the world, fighting for the rights of their heroes – can express what The Blur means to them and talk about why they believe in these super heroes.

• “Smallville” producers and the CWTV.com team will review the submissions and select a number of the user-submitted videos for broadcast as the testimonials that Clark watches during the “Beacon” episode airing Friday, February 4 (8:00–9:00 p.m. ET/PT) on The CW.

• In addition to selecting the winning videos to be used in the episode, the “Smallville” producers and CWTV.com team will also select a number of additional favorite videos that will be posted to CWTV.com following the broadcast.
